Application filed May 20,

invention is particularly applicable to metallic frames for n'hat are known as double hung Windows, including a v jamb fralneln whlch two sash frames are mount- ,7 5 ed to reciprocate parallel with each other.

nAs hereinafter described, my invention relates.particularly..to means for maintainv,ing. the sash frames in Weather tight relation with the amb frame, without interferio ing With the freedom of said sash frames for, reciprocation. I Such means include What.I term a Weatheringstrip which is. preferably, detachably ;c onnected with the jamb' frame and has] oppositely extending .rfianges overlapping and intereng'aging flanges upon the inner side of theouter sash i frame and upon the outer side of the innersash frame;

- My invention includes the various novel 20. features of construction and arrangement hereinafter more definitely specified.

. In said drawings; ig. I is a front elevation of a typical embodiment of my invention in, a WiDClOW frame including a jamb ,frameand two-sash frames. 7

It maybe observed thatfsaidiveath v strip 36 is formed of pressed meta very resiliently engagesaid sash frames andlthus much thinner than;the,metalofsaidg sash 1 frames'38 and'39; soas to be, flexible and not, only. practically hermetically f sealithef joints'between said weathering .stripfand sashes,' but also preventrattling9f said sashes. p 1 1,

As shown in Fig; II; said upper'sash.

' frame 38has its top rail 47 formed of a hollow pressed sheet'metal member with the folded'fiange 4i8 which, in cooperation with I the drawn steel hollow molding 49 retains adapted to shed rain. has the channel formed therein to receive the glass, panel 50 which is imbedded in putty or other suitable cement 51 between said flange 48 and molding 19; Saidsash frame '38 has the'bottom meeting rail 53 which is a hollow pressed sheet metal memher having the drip fiange 5 1 which is Said meeting rail 53 v the lower edge of said glass panel 50 which is 'imbedded' in cement 56 therein. 'Sa'id 'meetingrail 5'3'also has the channel 58 with .thesealing flange 59fhaving the lip 60 to facilitate its engagement with the sealing flange 6101a the top rail 62 of the sash V ,frame 39. Said top rail 62'is a doublechan- 'nelformed of pressed sheet metal, with the {inside flange 6&upturned,]and the inter- ;"i'nediate folded flange 65 extending downwardly to cooperate with the drawn steel molding 66 to hold the glass panel67, which is imbedded in the cement 68betweensaid flange 65: and molding 66.

Said .sash frame 39 also includesthe bottom rail 70, which is a hollow pressedsheet 1 iiietal channel having the upturned folded .fiange 71' which cooperates with the drawn steel molding 72 to hold the lower edge of said glass panel 67 between them, imbedded in the cement 73. The inner web75'of said bottom rail 70 isturned outwardly to form lithejfia-nge 76 which slides over said sealing .Qfiaiige'lO on said sill 8. The outer web 7 8,

of said lower sash rail 70, is similarly turned -'outwardly to form the flange 79 to cooperate the advantage of resilient flexibility, such asto minimize the-frictional engagementiof the sashes in the window frame, and thus' *permit them to be freely operated with the with the sealing flange 11 on saidsill;

' c; lherefore, it is to be understood that the Q 1, Construction and arrangement above de-' scribed are such as to practically hermeticallyj seal the sashes 38 and 39 not only at '-"their;junctions with said jamb frame, but

fat their junctions with each other. i

It may be observed'that theessential feature of the weathering strip 36 above den scribed is that it includes oppositelyprojecting flanges which interengage with suitable flanges {on the respective. sashframes; Although the dfshaped cross section of said interen a 'ed flan 'es' shown in Fi 111 has i b 1 7 b 7 ,minimum. amount of friction; such con- -struct1on of weathering strip 1s not sufiiciently rugged for some buildings There- 'fore, the" high degree of flexibility which is characteristic of the structure shown in Fig.

111 may, in some instances, be sacrificed to afford more rugged constructions vand arrangeme'nts, for instance, such as shown in Figs 'lv and V. s

with and yieldingly engage said sash frames Referring to, the form of my invention shown in Fig. IV; the weathering strip 81 is similar to said weathering strip 36, except that it is double-L shaped instead of doublefishaped. The oppositely extending sealing flanges 82 and 83 of said strip 81,

which are conveniently formed of double thickness of the metal by folding the latter,

are parallel with the main web of said face 'iexible than the weathering strip '36, but is sufliciently flexible and resilient to cooperate STsand 88.

However, it is notnecessary to have'the weathering strip between the sashesjreslllent to have it perform the sealing function here- 1 in contemplated. For instance, astill more rugged construction and arrangement is shown in Fig. V, wherein the weathering strip 90, instead of-being formed of pressed sheet metal, like the strips 36 and81 above described, is formed of a hot rolled, preferablysteel, angle member with oppositely ex tending L-shaped sealing flanges 91 and 92, which are adapted to cooperate with sash sealingflanges and 86, such as described with reference to Fi IV; Of'course in the construction shown in Fig. V longer screws, 93, 7 must be substituted for the screws 37 shown in Fig. III, to 'detachably hold the V weathering strip 90 in rigid relation with c the jamb frame 1.

It may be observed that in each form of my lnvention above described, a weathering strip is provided extending as a parting strip between the sashes and having sealing flanges extending transversely to the plane or the window frame and sashes constructed and arranged for resilient sliding engagement with sealing flanges upon said sashes and,"in'the form of my invention shown in Fig. 111, such sliding engagement is effected in (respective v planes frame and sash and to each other.

Therefore, I do not desire to limit myself to the "precise details of construction'and arrangement herein set forth, as it is obvious that various modifications may be made therein, without departingfrom the essential features of my invention, as defined in the appended claims. 1 claim:

which are obliquely transverse to the planeiof'said 1. In a window frame, the combination with a jamb frame member formed of sheet metal including a hollow guide rail and a sash frame member v including a resilient.

In testimony whereof, I have hereunto signed my name at Philadelphia, Pennsyl-l vania, this 17th day of May, 1922.
